UC Black Technology: Lasers make electronic devices no longer dependent on semiconductor materials

According to foreign media reports, the University of California, San Diego, scientists have developed a new type of microelectronic devices, the future of PC processors made of semiconductor materials may be replaced.

This new technology is still in its early stages of development, but it involves some interesting research and considerable science fiction concepts. University of California, San Diego engineers developed a light-controlled microelectronic device that contains metamaterials composed of gold nanotubes. By laser irradiation, the super-surface energy to produce high-intensity electric field.

This new type of microelectronic device, which does not use semiconductor materials, will someday solve one of the problems faced by modern microprocessors. The problem with processors that operate electronically depends on the fact that the electrons collide with atoms constantly, many of which may not be able to migrate to their destination - many electrons are lost during the processor's operation.

This new microelectronic device attempts to solve this problem by "mimicking" the old-fashioned vacuum tube - of course on a microscale. Mushroom-shaped nanotubes in the device form Metasurfaces on silicon wafers, both separated by a layer of silicon dioxide. When a low DC voltage is applied and a low-energy infrared laser is applied, this structure produces a high-intensity electric field that allows electrons to "migrate" freely.

This experimental technology enables more electrons to be controlled at a time with less interference, which means that processors built using this technology will outperform current semiconductor-based processors. This technology, which is still used in smartphones for quite some time, is an interesting concept and approach to solving the almost no-questions of modern electronic devices.
